Numbness?

I'm an 18 year old male, and excluding my little dilemma, I'm in absolutely perfect health, I watch what I eat to the point where I can't recall the last time I had fries or a piece of candy. I'm also an All-American rugby player, which demands certain physical stamina and endurance, so I exercise everyday for a considerable amount of time and to a considerable degree. However, two days ago I noticed a numbness on the left side of my left calf, from the top to the bottom. I thought it wasn't a big deal so I decide to ignore, however, today my middle finger is sore when I bend it, and the left side of my neck is equally tense. Does anybody have any possible explanations?

Hi;

   If all occurs on the same side, maybe see a Neurologist.
   If flucuating and sometimes apparently normal, I'm thinking some peripheral neuropathy issue caused by?
   Again, Neurologist.
   Have you injured yourself in any way?
